Product Feature<\/h2>\n

\u25c6Circuit breaker is designed with small volume,fully-closed structure,unique packaging technique of arc chamber and good sealing performance, which is suitable for use in high temperature and wet area.<\/p>\n

\u25c6The breaking performance of circuit breaker is steady,which has feature of inflammation, non-explosive danger, safe, maintenance-free light weight, long service life (10000 time), etc.<\/p>\n

It’s set with two-phase CT which outputs two-phase current, for information analysis by intelligent controller.To fulfill its function of over-current protection.CT ratio from 50\/5 to 600\/5, user can choose as per actual requirement.<\/p>\n

\u25c6It’s set with closing surge elimination device (compound controller), not only avoids malfunction caused by surge.<\/p>\n

\u25c6It can set with intelligent switch controller also, which has many protecting function like three-stage current protection,Zero-sequence protection,r eclosing,interrupting protection, etc.<\/p>\n

\u25c6It supports many kinds of protocols, which can be chosen to generate communication network,not only can it do manual operation locally and remote control to switch, but it also fulfills remotecontrol by communication network.lf it’s equipped with relative recloser or breaker controlling device, which can be used as recloser or breaker.<\/p>\n

\u25c6The operation mechanism is set inside of switch box,it avoids rust of mechanism effectively under long-time outdoor condition.<\/p>\n

\u25c6Column-mounted installation.<\/p>\n
